Über dieses Buch

This open access book considers the water, energy, food (WEF) nexus in the Pacific region. The region comprises seventeen sovereign countries and seven territories spread across the Pacific Ocean, a blue expanse that covers a fifth of the world’s surface area but contains only 0.5% of the population—or 44.5 million people. The uniqueness of the Pacific and the need for a Pasifika-led approach to sustainability across environmental, societal and economical spheres requires this blue continent to be considered in a separate volume under the ‘Water Security in a New World’ series.
This Pacific volume is focussed on water, energy and food security in Pacific Island Countries and Territories (PICTs) and the challenges produced by the impacts of anthropogenic climate change and human population pressures. The diversity of culture, traditional knowledge and ways of life across the Pacific are united by similar geographies and opportunities to apply a ‘Pacific specific’ WEF nexus approach; a coordinated approach to manage water, energy and food that is centred on active decision making across the three sectors to increase the security of each. Importantly, a WEF nexus approach builds on national and international efforts to date in the Pacific which include Integrated Water Resource Management, Ridge to Reef, Source to Sea, UNESCO Biosphere Reserves, Integrated Coastal Zone Management and other similar approaches.
In this book, contributions by authors from governments, regional bodies, multilateral agencies, and academia describe water security and its intersectionality with both the energy and food sectors, highlighting the significance of both land and marine food systems and connectivity between water and energy in a Pacific-focussed context. It is demonstrated that these systems cannot be separated from the challenges associated with healthy environments and functioning ecological services, transport, and waste that are unique to this vast archipelagic region. To achieve meaningful change, it is essential that solutions are cognizant of the world’s colonial past and the global inequalities that persist today. The path forward for water and food systems is one that is Pasifika-led and builds on traditional knowledge and local capacity. National energy demands must consider the future with solutions comprising both WEF-integrated approaches and new energy technologies to hasten the transition away from fossil fuels. Globally, major greenhouse gas emitters both past and present need to step up for the environmental and economic benefit of all by rapidly reducing greenhouse gas emissions and supporting Pasifika leadership on highly ambitious net zero goals.
This book is a highly recommended source of information and inspiration for policy makers, decision makers, research communities and practitioners dealing with any aspect of water, energy, or food security in the Pacific.

Chapter 1. An Introduction and Overview to Building Water, Energy, and Food Security in the Pacific Using a Nexus Approach
Abstract
The Pacific is not on track to achieve any of the SDGs by 2030 with major progress needed across each of the environmental, societal, and economical realms. Progress towards certain SDGs should not come at the expense of others and adding further complexity, new methodology are now also being developed to meet more recent national targets under the 2050 Paris Agreement net zero greenhouse gas emission aspirations. A water, energy, food (WEF) nexus approach provides a framework with which to increase the security of each of the three sectors, underpinned by a healthy environment and recognizes the role and need for functioning ecological services. The blue carbon market offers a particularly well-suited opportunity for the Pacific to combine sound environmental stewardship with economic opportunity and follow-on societal benefits. This unique ‘blue continent’ of islands and archipelagos spread across the Pacific Ocean requires a regional-specific consideration of the WEF nexus often overlooked as part of the larger ‘Asia–Pacific’. However, applying a WEF nexus approach in the Pacific is not a one-size-fits all undertaking. Discussed in chapter-specific detail in this volume, it requires country- or territory-specific consideration of existing water resources, food systems, energy needs, and traditional knowledge while addressing challenges from anthropogenic climate change, human population growth, and ever-increasing demands for resource consumption.

Chapter 2. State of Freshwater Resources in the Pacific
Abstract
The freshwater resources of Oceania are highly variable, comprising some of the global extremes in terms of availability and access. The Pacific Island Countries and Territories (PICTs) have lower water security than Australia and New Zealand, the two developed nations in the region. Among PICTs, whilst surface and groundwater resources are available on high volcanic islands, small, low-lying coral and limestone atolls have limited groundwater and no surface water, hence are highly dependent on rainfall. Almost all islands utilize groundwater if not for potable purposes, then for washing needs. The development of water resources for human uses has focused largely on urban centres, whilst smaller and remote communities in PICTs often lack basic water services. Available water resources are also subject to multiple threats, mainly from untreated human and mine wastes, agricultural chemicals, and sediments from forestry operations. Freshwater lenses in PICTs are facing saline intrusion resulting from over-exploitation, sea-level rise, and storm surges. Climate change is altering long-term rainfall and evapotranspiration patterns and exacerbating extreme events such as cyclones, floods, and droughts. The small populations, limited financial resources, and low capacity across the water sector in PICTs, continue to inhibit progress with SDG 6, despite considerable donor support.

Chapter 3. Energy Security in the Pacific
Abstract
Energy security is a multifaceted concept, depending on whether the perspective is national or household level, urban or rural, higher or lower income, commercial or individual. Energy security in the Pacific Island Countries and Territories (PICTs) has progressed in some areas such as energy access and renewable electricity generation but less in others such as affordability and energy efficiency, while a significant dependence on petroleum imports remains. New aspects of energy security are emerging, notably climate resilience, transport, and gender. Better data can inform evidence-based decision making but the cost and effort against the available capacities for data collection and analysis must be considered. While continued investment is needed for renewables and energy efficiency, a greater shift in climate finance towards adaptation and development of resilient energy systems in the PICTs is vital. Finance must also be found for securing petroleum supplies and their safe use while they are still needed.

Chapter 4. State of Food and Nutrition Security in the Pacific
Abstract
Pacific Island Countries and Territories (PICTs) are home to tremendously diverse food systems. These systems are made up of rich cultures, a growing young population, and diverse bio-geographic and multiple agro-ecological zones. This Pacific uniqueness, however, is being disrupted by historical international forces, food consumption behaviours, and climate change. The region’s food systems currently face a triple burden of malnutrition, which when combined with poverty and climate change impacts, creates major food and nutrition security risks. In this synthesis chapter, we provide summary of evidence on the state of food and nutrition security in the Pacific using an expanded five pillar framework of food security. We present a synthesis of research and development dynamics in the context of availability, accessibility, stability, utilization, and agency as the five pillars of Pacific food and nutrition security. Agency is emphasized as a novel addition to capture the unique socio-cultural systems of the region that contribute to food systems. The future of Pacific food systems will depend on proactive focus on the multi-dimensional nature of food and nutrition security, and the use of integrative frameworks and policies will help address this important development opportunity.

Chapter 5. Regional Climate Drivers, Trends and Forecast Change
Abstract
Hydroclimatology across the Pacific depends on the rain-generating South Pacific Convergence Zone and Intertropical Convergence Zone. These convergence zones move northward and southward over time (described by the El Niño Southern Oscillation index), which results in naturally high variability in rainfall, wind, tropical cyclone risk, and sea level. Future changes in convergence zone dynamics will be important for Pacific Island populations but known climate model deficiencies make projections uncertain. Extreme rainfall will probably increase, potentially enhancing flood risk, but drought risk is likely to decline in most countries. Average temperatures will be warmer in the future and marine heatwaves, together with ocean acidification, could threaten important coral reefs and fisheries. Sea level rise presents a key threat to small island nations due to saline intrusion and flooding. Global greenhouse gas emissions must be urgently reduced to avoid the worst impacts on Pacific Island nations. Local communities often have a deep understanding of their surroundings built over many generations and they are highly resilient to variable conditions. Therefore, adaptation strategies should respect and leverage traditional knowledge to maximise their effectiveness.

Chapter 6. The Water-Food Equation in the Pacific
Abstract
On land and in the sea clean water safeguards food and nutritional security in the Pacific, because it underpins functioning, productive food systems, and human health and wellbeing. Water, food, and communities in the region are intrinsically connected, which makes resolving ecological and socio-economic issues an inherently complex task. Yet, this connectivity, and the geographic diversity of Pacific nations, is also a strength. Nexus solutions can be effective in increasing the sustainability of resource use and the resilience of ecosystems and communities to climate change, as they enable a range of interconnected land and sea ecosystem issues to be considered across multiple spatial scales. They also support communities, governments, and industries to identify and navigate trade-offs in social and ecological objectives. This chapter explores challenges in the water-food equation and several nexus-focused strategies that could foster sustainability and the resilience of ecosystems, resources, and communities in the Pacific.

Chapter 7. The Water-Energy Equation
Abstract
In 1994, Peter Gleick defined the intricate relationship between water and energy as this: “We use energy to help us clean and transport the fresh water we need, and we use water to help us produce the energy we need.” In the Pacific region, where diesel fuel is the primary electricity generation fuel, the water-energy nexus goes further. Globally, large quantities of water are needed to produce the fuel required to electrify the Pacific region. The prevalence of piped water systems in the Pacific region depends on a country’s electrification rate. Renewable energy technologies can increase rural electrification rates. A positive statistically significant relationship exists between a country’s electrification rate and the prevalence of piped drinking water systems, which gives hope that adopting aggressive renewable energy and climate policies will lead to greater access to improved drinking water sources across the Pacific region.

Chapter 8. Desalination in the Pacific
Abstract
Desalination has traditionally underpinned public water infrastructure in the Middle East and is now an important component of urban water supplies for communities in Asia, Southern Europe, the Americas, and Australia. However, the deployment of this technology in the Pacific at scale has mostly been used to support defense installations, mining operations, and tourist resorts. Drawing on data from more than 60 facilities, this chapter charts the use of seawater desalination as a source of freshwater in the Pacific. Beginning with the first installation of a multistage flash distillation system in 1964 on Hao Atoll, French Polynesia, the chapter summarizes the features of the thermal distillation and reverse osmosis desalination systems deployed in Polynesia, Micronesia, and Melanesia, as well as the motivation for the projects, institutional arrangements, and current operational status. At present, the utilization of desalination in the Pacific per capita is lower than other countries of comparable gross domestic product (GDP) and water vulnerability as defined by the United Nations Environment Programme (UNEP). While non-government actors, including sovereign and international development banks have plans to develop desalination facilities, a variety of obstacles prevent the wider distribution of the benefits of this climate-resistant water source. The chapter examines the potential applications of desalination in enabling economic activity, reducing pressure on freshwater resources.

Chapter 9. Towards a Circular Logistics Partnership: Regional Trade, Waste, and Inter-Sectoral Cooperation
Abstract
Trade in the Pacific connects economies and communities, but also relies on profitmaking transactions. An outcome of this is that waste and no-longer-wanted goods build up on island nations and if not properly managed are directly detrimental to water resources and communities, and indirectly to tourism-driven revenue, upon which many Pacific Island Countries and Territories (PICT) depend. The logistics of distances exacerbates these issues. Careful analysis and leveraging slacks in the logistics systems helps not only improve economic efficiencies through recycling, but also reduce in situ waste streams. However, implementation of a circular logistics system requires strong partnerships between Governance, Science and Business working together. This chapter details a case study in the PICT to load empty shipping containers with refuse for recycling when they are relocated back to the Pacific Rim for reloading with more finished goods for import to PICT. Building on the above, a proposed project to manage the disposal of the increasing numbers of end-of-life vehicles, batteries, and other light grade metals in the Pacific will also be described. This is notwithstanding that the preferred method of avoiding disposal by abandonment is to legislate for Extended Producer Responsibility (through extended Advanced Disposal Fee (ADF) schemes) to engineer the issue away at source.

Chapter 10. Infrastructure Vulnerability to Disruption: A Particularly Pacific Problem
Abstract
Infrastructure and climate have important roles in driving the water-energy-food nexus in the Pacific region. The significance of infrastructure is woven throughout the United Nation’s 2030 Agenda for Sustainable Development, with Sustainable Development Goals relevant to infrastructure and its links to the water-energy-food nexus. Pacific Island Countries and Territories (PICTs) differ from larger developed neighbouring countries in Oceania such as Australia and New Zealand, bringing about a unique set of challenges for infrastructure. Physical characteristics include small, remote populations and small land masses, and susceptibility to natural hazards. Institutional challenges such as governance, small economies, and limited infrastructure expertise are prevalent. Yet, despite all these challenges, climate change is perhaps the largest. This chapter considers the interconnectivity of infrastructure and the water-energy-food nexus, and the importance of building climate resilience within the infrastructure sector reflected through the lens of three key infrastructure areas namely maritime transport, coastal protection, and Water, Sanitation and Hygiene (WaSH) infrastructure.

Chapter 11. Adapting to Change? Traditional Knowledge and Water
Abstract
Pacific Islander communities need to maintain traditional knowledge and practice about their water systems, despite the ongoing legacy of colonial impact, in order to adapt to climate change where its impacts will significantly impact water quality and reliability. Without healthy water systems, Pacific communities will become increasingly vulnerable. Traditional knowledge has a role to play in building the adaptive capacity of islanders to water shortages and in adapting to climate impacts over time. While colonization, belief in God, and loss of traditional knowledge are barriers to effective adaptation, Pacific Islanders across the region are using existing traditional knowledge in combination with other knowledge systems to build resilience to climate change and innovative adaptation solutions. Approaches informed by traditional knowledge enable the incorporation of localized, detailed, and historical knowledge, and experience into contemporary management regimes, which then enable the development of tailored and appropriate place-based adaptation. Importantly, the use of traditional knowledge also strengthens community receptivity to adaptation initiatives.

Chapter 12. Energy Transitions
Abstract
This chapter addresses the opportunities for the Pacific region nations and territories to participate in the global transition from fossil to renewable energy supplies and, in so doing, gain greater autonomy, resilience and more equitable energy supplies and reduced contributions to the evolving crisis arising from excessive atmospheric carbon. Most of the region’s jurisdictions have made little historical contribution to that problem but many are particularly vulnerable to its impacts. A set of critical energy capture and conversion technologies is examined in the Pacific context, as are some key energy services in actual or potential transition, before examining progress and potential for improved policy, regulation, and support, such as technical training. Much has been achieved but much remains to be done and a supportive multinational effort is required to realize the potential.

Chapter 13. Secured WEF and Gender: Better Data for Equality and Resilience
Abstract
Under increasing climate uncertainties and extremes, threats to water, energy, and food (WEF) security affect vulnerable social groups in disproportionate ways. In the Pacific region, women and girls continue to be disadvantaged in access to water, sanitation, and hygiene services; in their decision-making power over natural resources management, and in developing their full potential for economic autonomy. Gender disparities are usually based on structural inequalities rooted in cultural norms, social stratification, and relations of power. Sector analyses often do not adequately reflect how the WEF security nexus and gender interrelate. One main factor conditioning ill-informed sector analyses is the lack of sex-disaggregated data. The chapter briefly discusses availability of gender disaggregated WEF-related data in the Pacific region with a focus on the Pacific Small Island Developing States. It then proposes an integrative gender methodology for the analysis of natural resources management and agricultural development programmes for policy and project development. Useful methodological tools for disaggregating data by gender are further discussed.

Chapter 14. Poverty in the Pacific: Trends, Progress, and Challenges in the Early Twenty-First Century
Abstract
Poverty persists in the Pacific but is characterized less by standard international measures of absolute or chronic deprivation than by vulnerability and volatility. Communities in the Pacific are generally small and remote, creating challenges for the provision of basic goods and services. Their economies rely heavily on external economic relations—trade, employment, and remittances and tourism and aid—including for essential commodities such as food and energy. Among sources of vulnerability, environmental degradation, loss of biodiversity, and climate change impacts expose nations to shocks, often generating disasters which undermine the livelihoods of households. Over the past three decades progress has been made in reducing poverty and improving well-being; however, significant problems persist related to health and nutrition, access to services, employment, and livelihoods, and most countries have been slow to expand social protection systems to protect the most vulnerable. The Sustainable Development agenda offers the possibility of alternative development strategies that could favour ocean economies. However, this will require significant development assistance and investment from the international community at a time when aid budgets are coming under pressure from COVID-19. The global pandemic, with its travel, trade, and tourism restrictions, highlights the region’s susceptibility to external shocks and is reversing recent gains in poverty reduction.

Chapter 15. Living in Oceania
Abstract
The ever-increasing impacts of climate change have once again reignited the growing debate on natural resource scarcity in the Pacific Island Countries and Territories (PICTs). New scientific findings repeatedly suggest the situation is grave as we continue to push planetary boundaries for the sustainable use of natural resources, threatening natural systems and our own existence. In the PICTs the situation is especially critical, given the current and forecast impacts of climate change (Chap. 5) on these island nations. In an island setting where resources may be limited and vulnerable the issue of security requires appropriately scaled attention. Confounding this is a multitude of pressures presenting a complex problem of demand. Key pressures faced on many PICT resources are increasing human populations; competing demands; the emergence of new opportunities, markets, and consumers; the fragmented nature of resource governance; and climate change. These illustrate the new realism of physical and economic scarcity of resources we face in the era of globalization, even across the geographically vast region of Oceania. Amongst this, water, energy, and food (WEF), are most critical to the region. These three resources are critical for human sustenance, essential separately but intrinsically connected in their use and management needs. This resource and policy nexus must be actively managed as its mismanagement and insecurity impede social stability and economic growth for the region. This chapter aims to understand the applicability of the WEF nexus in the PICT context. This considers both nexus experience in the PICTs to date and the opportunities and challenges the WEF nexus presents in its operationalization specifically in a PICT context.

Chapter 16. Nexus as a Lens for SDG Implementation
Abstract
Water is profoundly linked to the development and sustainability of all nations. It forms a natural connection across the Sustainable Development Goals, all sectors of the nexus, and even between countries. The Global Environment Facility (GEF) International Waters focal area realizes that the water, energy, and food nexus can be both a source of tension and an entry point for cooperation. The GEF works with island countries to tackle the nexus through an ecosystem-based approach known as Ridge to Reef (R2R). This chapter highlights some of the practical on-the-ground solutions demonstrated by national projects and how the GEF-UNDP Pacific Ridge to Reef Programme is creating entry points for enabling the water, energy, and food nexus that are aligned with the Sustainable Development Goal outcomes.

Chapter 17. UNESCO-Designated Sites in the Pacific
Abstract
UNESCO-designated sites—Biosphere Reserves, World Heritage sites, and UNESCO Global Geoparks—represent a multi-tier commitment by UNESCO, national governments, local authorities, and communities towards the protection of natural and cultural heritage as well as to the development and sharing of innovative approaches to sustainable development. In the Pacific, the establishment of UNESCO-designated sites over the past two decades has intersected in multiple ways with the vast array of local and indigenous knowledge systems and practices governing and guiding the relationship between people and their environment. With specific reference to water, energy, and food, this chapter examines the role and functions of UNESCO-designated sites in Pacific Island Countries and Territories (PICTs), their engagement with local and indigenous knowledge and practices, as well as with existing protected area initiatives.

Chapter 18. Clean Energy Options for the Future
Abstract
While the transition to a cleaner energy sector is underway in Pacific Island Countries and Territories (PICTs), there are still many challenges that need to be overcome from demand, energy, chemical, and technological perspectives. The composition of the Pacific region makes it highly compatible with the movement towards small-scale, decentralized, and on-demand production of chemicals (for direct use as well as acting as an energy storage vector). Power-to-X, being the conversion of electricity into a range of different chemicals and fuels, has immense potential to offset reliance on imports, fossil fuels, as well as decrease transportation requirements. The emerging Power-to-X technologies have potential to address many of the struggles in transforming to a renewable sector. This chapter examines the transition to clean energy generation technologies, focusing on those emerging technologies which are close-to-market level implementation and have the potential to transform the Pacific region. The prospects and limitations, including the diversity of the region from both a generation and storage perspective, as well as the chemical demand, and its reliance on fossil fuel-based derivatives and imports are discussed.

Chapter 19. Geothermal Energy for PICTs
Abstract
The following chapter explores the utilization of geothermal resources to provide energy, food, and water solutions in both urban and rural populations in the Pacific—several of which have vast geothermal reservoirs. A variety of geothermal-based technologies are presented providing alternative approaches to essential services such as electricity, food drying, refrigeration, and desalination. A set of design principles for geothermal solutions in the Pacific is also outlined and explored in further detail via a brief pre-feasibility case study for a geothermal village development on Tanna Island, Vanuatu. Finally, the opportunities of direct heat using underground geothermal implementations are discussed, indicating that these may well be an excellent means to provide low-cost solutions to rural areas, reduce investment risks associated with deeper geothermal well drills, and recycle waste heat to provide a wide range of services.

Chapter 20. Towards Food, Nutrition and Income Security in Papua New Guinea Through Inland Fish Farming
Abstract
Malnourishment and undernourishment are prevalent in Papua New Guinea, leading to disease, lower quality of life and less opportunity. Protein deficiency in diets is a pervasive problem in PNG. Inland fish farming was introduced as a means of increasing access to locally produced protein, particularly for rural people who are poor and most impacted by diet-related health problems. Over the last decade there has been rapid growth of fish farming attributed to development interventions that facilitate adoption of better farming practices. The high cost of feed, poor supply of quality fingerlings, lack of infrastructure, and limited access to technical knowledge are bottlenecks to fish farming that are being tackled by Government, NGOs and donor funded programs. Inland fish farming has also generated social benefits such as reduced crime and tribal fighting, introduced a second income for families, and increased access to better education and health services.
